Venetian Blind Repair Tool

ABSTRACT

A tool for repairing Venetian blinds comprising a cradling member and a receiving member which moves relative to the cradling member. The cradling member has a horizontal portion and a vertically extending portion. The cradling member has a protrusion located a distance away from the ledge for supporting a portion of the Venetian bond. The receiving member slides up the cradling member towards the edge. The edges of the Venetian blind are compressed towards each other between the extended ledge and the receiving member to re-introduce a curvature to the Venetian blind.

FIELD OF THE INVENTION

This invention relates to the field of repair solutions for Venetian blinds.

BACKGROUND OF THE INVENTION

Venetian blinds comprise thin slats which are often made from metal. Damage, such as bending the slats out of shape, frequently occurs during the normal course of use. Slats may be damaged by repeated use, or by accidental compression, such as during cleaning. Current repair solutions for Venetian blind slats include attempting to bend the slats back by hand without the assistance of a tool, or by disassembling the blind to replace the damaged slats. Each of these solutions is disadvantageous for various reasons. Hand bending the slats in an attempt to match the original curvature or the undamaged portion often results in uneven and off-center bends, which can cause more damage to the blinds. Replacing the damaged slats can be time consuming and results may not be satisfactory since the new slats may not match the color of the original slats which have faded over time. As a result, replacing the entire set of Venetian blinds is often the most effective solution. However, replacing the entire set of Venetian blinds is not a cost effective solution.

The present inventor has recognized the need for a tool for repairing Venetian blinds.

The present inventor has recognized the need for an easy to use tool for re-introducing a curvature to the Venetian blind.

SUMMARY OF THE INVENTION

A tool for replacing Venetian blinds comprising a cradling member and a receiving member which move relative to each other. The cradling member comprises two arms separated by a slot. An extended ledge which forms the inwardly bent L-shape at the front end of the cradling member extends from the base of the cradling member. The prongs each comprise a protrusion for supporting a portion of the Venetian blind. The protrusions are disposed a distance away from the extended ledge. The receiving member receives the back end of the cradling member opposite the end comprising the extended ledge, within a recessed region. The depth of the recess in the receiving member which receives the distal end of the cradling member is of a sufficient depth to allow the leading edge of the receiving member to slide upwards on the cradling member towards the ledge a desired distance. The distal end of the cradling member has at least one recess which engages with a spring. The spring biases the cradling member and the receiving member in an extended position such that when the receiving member is moved towards the curve forming position, the receiving member is inclined to move back into its starting position and is ready for use again.

Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims and from the accompanying drawings.

DETAILED DESCRIPTION

While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

FIG. 1 illustrates a perspective view of the blind repair tool 10. The blind repair tool comprises a cradling member 20 and a receiving member 30 which move relative to each other. The cradling member comprises two arms 25 separated by a slot 40. The extended ledge 50 which forms an inwardly bent L-shape at the front end 55 of the cradling member extends upwards from the base 60 of the cradling member. In the embodiment show in FIG. 1, ledge 50 extends from the base at an angle “α.” The extended ledge 50 intersects the base 60 at a straight edge 51. As illustrated in FIG. 1, angle “α” is less than 90 degrees, and is tilted towards the back end 56 of the cradling member. In another embodiment illustrated in FIG. 2, the ledge 50 a extends laterally past the width of the prongs 25 a. In another embodiment, the ledge can extend at an angle 90 degrees or greater from the base 60 of the cradling member.

The prongs 25 each comprise a protrusion 70 for supporting a portion of the Venetian blind within the curve forming region 110 (FIGS. 3 and 4). In the embodiment shown, the protrusion 70 has a rounded surface 71. In one embodiment, the protrusion is semi-cylindrical. The central axis of the semi-cylinder is located at distance D from the edge wherein the ledge 50 extends from the base. In one embodiment distance D is half the width of the Venetian blind slat being repaired. For wider slats, distance D is greater. In other embodiments, the protrusion need not have a cross sectional area that is half the area of a circle, and can have a cross-sectional area that is greater or less than a semi-circle. Any other suitable shape for the protrusion can be used.

The back end 56 of the cradling member 20 is received within the receiving member 30. The receiving member 30 comprises a recessed region 80 (shown in dashed lines in FIGS. 1 and 3), or pocket shaped to receive the back end 56 of the cradling member. In the embodiment illustrated in FIG. 1, the back end 56 of the cradling member has two slots 90 to receive springs 95. Springs 95 can be tension springs which allow for the cradling member and receiving member to be biased towards an extended position wherein the back end 56 of the cradling member 20 is not in contact with the end 85 of the recessed region 80. Any other method of engaging a spring mechanism between the cradling member and the receiving member can also be used. Any other mechanism for returning the cradling member and the receiving member into an extended position can also be used. In other embodiments, the cradling member is disposed beneath the receiving member while the receiving member moves along the top surface of the cradling member without comprising a recessed region which engages with the back end of the cradling member.

In one embodiment, the receiving member 30 has a leading edge 120 with an angled surface 121. As illustrated in FIGS. 1 and 4, the angled surface 121 intersects with the base 60 of the cradling member 20 at an angle “β”. Angle “β” as illustrated in FIG. 4, can be less than 90 degrees. In other embodiments, β may be 90 degrees or greater. In some embodiments, angles “α” and “β” are equal. The angled surface 121 contacts the base 60 at a straight edge 122. In one embodiment, straight edge 122 and straight edge 51 are parallel and on opposite sides of the protrusion 70.

In use, the user places a portion of the Venetian blind 100 for which repair is desired across prongs 25. The user aligns one edge of the Venetian blind against the straight edge 51 formed by the intersection of the extended ledge 50 and the base 60, such that a central portion of the Venetian blind 100 is disposed over the protrusion 70 within the curve forming region 110 (FIG. 4). To generate a bend in the Venetian blind, the receiving member is moved towards the Venetian blind in a direction “A” as indicated by the arrow in FIG. 4, to pinch the edges of the Venetian blind 100 towards each other to re-introduce a curvature to the Venetian blind. The Venetian blind as a result is pinched between the straight edge 122 formed by the intersection of the angled surface 121 and the base 60, and the straight edge 51 formed by the intersection of the extended ledge 50 and the base 60. Pressure from the receiving member is exerted as needed depending on the curvature desired, and the stiffness of the Venetian blind. Without wishing to be bound by any particular theory, it is believed that the force exerted on the Venetian blind edge as a result of the disposition of the Venetian blind between the extended ledge 50 and the angled surface 121 are more likely to be equal when the angles “α” and “β” are equal. The force actually exerted on the edges of the Venetian blind depends on the configuration or shape as a result of the extent of damage, of the venetian blind. The width “W” of the wingspan of the extended ledge 50 a (FIG. 3) and the width “S” of the receiving member can be the same or different widths, depending on the desired mechanical dynamics for the particular size and type of Venetian blind, which can have a varying stiffness and/or thickness.

From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
